Furthermore, the pipe body comprises an inner connecting pipe, a clamping groove and an outer connecting pipe, the inner connecting pipe is arranged in the middle of the outer connecting pipe, and the clamping groove and the outer connecting pipe are of an integrated structure.

Furthermore, the adhesive tape piece comprises a sheet body, a hollow opening and a fixed rod, the hollow opening and the sheet body are of an integrated structure, and the fixed rod is embedded and fixed at the inner wall position of the hollow opening.

Furthermore, the outer side of the inner connecting pipe is jointed with the inner side of the film.

Furthermore, the clamping groove is positioned at the inner side of the external pipe.

Furthermore, the surface of the inner connecting pipe is wrapped by a circle of steel sheet with smooth surface, so that the film attaching piece can rotate more smoothly.

Compared with the prior art, the utility model has the following beneficial effects:

when the adhesive tape is not attached to the back of the hand of the patient, the adhesive tape is rotated, so that the adhesive tape can rotate along the clamping groove until the adhesive tape is attached to the back of the hand of the patient, medical adhesive tapes can be conveniently pasted to fix the adhesive tape, and the condition that the needle head needs to be rotated when the adhesive tape is not attached to the back of the hand is effectively avoided.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

Examples

As shown in fig. 1 to 4, the utility model provides a puncture needle for outpatient service, which comprises an adapter 1, a puncture needle 2 and a catheter 3, wherein the adapter 1 is fixed at the tail end of the catheter 3, the puncture needle 2 is installed at the front end of the catheter 3, the puncture needle 2 comprises a film 21, a needle head 22 and a tube body 23, the film 21 is movably clamped at the side position of the tube body 23, the needle head 22 is installed at the bottom position of the tube body 23, the tube body 23 comprises an inner tube a1, a clamping groove a2 and an outer tube a3, the inner tube a1 is installed at the middle position of the outer tube a3, the clamping groove a2 and the outer tube a3 are of an integrated structure, the film 21 comprises a sheet body b1, a hollow b2 and a fixing rod b3, the hollow b2 and the sheet body b1 are of an integrated structure, the fixing rod b3 is embedded and fixed at the inner wall position of the hollow b2, the outer side of the inner pipe a1 is attached to the inner side of the adhesive sheet 21, the clamping groove a2 is located at the inner side of the outer pipe a3, and a circle of steel sheet with a smooth surface is wrapped on the surface of the inner pipe a1, so that the adhesive sheet 21 can rotate more smoothly.

The working principle of the present invention is explained as follows: the utility model can be connected with the conduit of the infusion bottle through the adapter a1, then the puncture needle 2 is inserted into the blood vessel of the hand of the patient through the medical staff, so that the liquid guide tube 3 can guide the liquid medicine in the infusion bottle into the puncture needle 2 under the matching of the adapter 1, then the liquid medicine is guided into the blood vessel of the patient through the puncture needle 2, when the adhesive sheet 21 is not attached to the back of the hand of the patient, the adhesive sheet 21 can rotate along the clamping groove a2 by rotating the adhesive sheet 21 until the adhesive sheet 21 is attached to the back of the hand of the patient, so as to be convenient for fixing the adhesive sheet by adhering the medical adhesive tape, the condition that the needle head 22 needs to be rotated when the adhesive sheet 21 is not attached to the back of the hand skin is effectively avoided, and the medical adhesive tape passes through the fixing rod b3 in a mode in figure 4, so that the contact area of the medical tape and the back of the hand skin can be increased, and the fixing rod b3 can press and fix the medical tape, thereby preventing the medical adhesive tape which is used for sticking the puncture needle 2 on the back of the hand from falling off in the process of infusion.
